Acetate Shock Loads Enhance CO Uptake Rates of Anaerobic Microbiomes
Microbial Biotechnology, Volume 17, Issue 12, December 2024.Pyrolysis of lignocellulosic biomass yields syngas and an acetate‐rich wastewater. This study examined high acetate levels during syngas co‐fermentation by anaerobic microbiomes at different pHs and temperatures. Microbiomes converted syngas at 64 g/L acetate and pH 5.5. Acetate supplementation increased CO conversion rates and altered product spectrum

Evaluating propionate production in Clostridium ljungdahlii inoculated bioelectrochemical system
Process BiochemistryBioproduction of chemical building block such as propionic acid (propionate) is of great interest in current time as it is a sustainable alternative to petrochemical synthesis. Clostridium ljungdahlii as an electroactive homoacetogen is able to ferment sugars or utilize CO2 to produce organic acids under bioelectrochemical system (BES).

Influence of Carbon Source Pre-Adaptation on Clostridium ljungdahlii Growth and Product Formation
Journal of Bioprocessing & Biotechniques, 2011 Syngas fermentation is considered an alternate processing method for biofuel and biochemical production as part of thermochemical biomass conversion. Exposure of syngas fermenting microorganisms to sugars, either in the primary syngas fermentation or through pre-adaptation in the seed culture, has the potential to enhance overall fermentation ...

Bioprocess development with Clostridium ljungdahlii based on metabolic modelling
Bacterial synthesis gas (syngas) fermentation offers a promising solution for the reduction of greenhouse gas emissions - the greatest challenge of today’s society. The substrate gas, which mainly consists of CO2, CO, and H2, represents an inexpensive feedstock originating from agricultural, industrial, and municipal wastes.
